Papers by Keyword: Orbital Order

Abstract: The charge density wave order in titanium diselenide is unusual in that it is characterized by a breakdown of inversion symmetry as well as translational symmetry, leading to the emergence of a chiral crystal structure. This novel state of matter was recently described theoretically in terms of the simultaneous and cooperative onset of both charge and orbital order. Here, we discuss the analysis of recent X-ray diffraction and related measurements on 1T-TiSe₂ in terms of the predictions of that theoretical model. It is show that the experimental observations agree with the expectations from an emerging combined charge and orbital ordered phase.

Abstract: We present resonant x-ray scattering experimental data from YVO3. By scattering at the vanadium K edge we are able to observe diffraction from the anisotropic tensor of susceptibility at the Bragg forbidden (010). The resonant energy spectra from these reflections are unusually complex, giving an indication of the crystal field distortions around the vanadium site.
